Title: Frame synchronizing equipment
Inventor: KUBO KAZUO
IPC: H04L7/08
Filed: 1990-04-09
Abstract: PURPOSE:To operate a low speed frequency division clock by controlling a frequency division ratio of a variable frequency division counter so as to rearrange a parallel data in a prescribed expansion order. CONSTITUTION:A received serial data (a) is stored sequentially in a shift register 8 while being shifted by a clock pulse (b). A variable frequency division counter 9 generates a frequency division clock (g) for each of n-set of the pulses (b). A latch circuit 10 latches a data in the register 8 at that time according to the clock (g). The data latched in the circuit 10 is outputted as a parallel data (e). The data (e) is given to a pattern detection section 2, in which a frame pattern is detected. The result of detection by the detection section 2 is fed to a frame synchronization section 3. When the data (e) is not expanded in parallel in a prescribed order, the synchronization section 3 changes its frequency division ratio with a load data (f) to the variable frequency division counter 9. Thus, the data (e) keeps a prescribed expansion order and the frame synchronization is maintained.

Title: Heat pipe
Inventor: TERAKADO MASAYUKI
IPC: F28D15/02
Filed: 1984-05-10
Abstract: PURPOSE:To permit to recirculate operating fluid efficiently through a recirculating pipe by providing a spiral operating fluid recirculating pipe in the axial direction of the heat pipe main body having the operating fluid. CONSTITUTION:The heat pipe main body 1 having the operating fluid is provided with the spiral operating fluid recirculating pipe 2 in the axial direction thereof. The heating side 1a of the heat pipe is positioned at the upper part, for example, and the operating fluid 4a, absorbed into a sintered metal 3a, deprives latent heat and is changed to vapor 5a. The vapor is diffused into the heat pipe and arrives at a cooling section 1c through a heat intercepting section 1b. The vapor 5c is changed into liquid 4c in a cooler and is absorbed into the sintered metal 3c. The liquid 4c drops into the spiral heat pipe 2c sequentially by the rotation of the heat pipe. The liquid 4c stays at a low position in the pipe 2c at all times, therefore, it arrives at the spiral pipe 2a through the same pipe 2b by the centrifugal force of the rotation, then, is sent out to the heating section 1a sequentially. Thus, a big amount of heat may be transferred continuously from the heating section to the cooling section.

Title: Ejecting device for floppy disk
Inventor: FUJIMOTO SAKAE
IPC: G11B17/041
Filed: 1980-07-09
Abstract: PURPOSE:To load a disk at a correct position corresponding to the closure of a cover while the disk is half-inserted, by permitting a movable block, coupling with an inserted disk, to self-control its movement with a prescribed control lever. CONSTITUTION:An inserted floppy disk presses a contact part 50 and a block 48 slides coupling with the disk. Then, a control pin 44 united with the block 48 slides on the 1st bevel 58A of a control lever 53, which oscillates to charge a lock spring 54 and an ejection spring 61. Further, when the pin 44 moves to the 2nd opposite bevel 58B according to the movement of the block 48, the movement of the block 48 is restrained automatically through a lever 53 turning by the charged force of the spring 54. Consequently, even when a disk is half-inserted, the disk separates from the block 48 near its normal position and is supported to be loaded at a correct drive position by a press-contacting member 82 formed on a taper surface when a cover 11 is closed.

Title: Arithmetic unit
Inventor: SUGIYAMA FUMIO
IPC: G06G7/161
Filed: 1979-07-24
Abstract: PURPOSE:To improve multiplication precision remarkably with a simple constitution by shifting the 2nd input signal in phase from the 1st input signal by a fixed value. CONSTITUTION:The 1st input signal Vi1 is input to integrator 2 by way of switch 1a. Reference signals Vr and -Vr are also input to integrator 2 selectively through switches 1b and 1c. The output of integrator 2 is input to comparator 3. This comparator 3, when the output of integrator 2 is greater than a comparison reference level, generates a signal of level H, which is supplied to switch control circuit 4 to perform pulse-width modulation that corresponds to signal Vi1. Input signal Vr2, on the other hand, is phase-delayed through phase circuit 6 and then input to integrator 7 through switch 5 turned on-off with the output of circuit 4. This integra- tor 7 outputs the products of signals Vr1 and Vr2. Thus, signal Vr2 is delayed by a certain time width to eliminate equivalently sampling time difference from signals Vr1 and Vr2, so that a high-precision arithmetic value can be obtained.

Abstract: PURPOSE: To recover easily a pure oil component alone free from impurities such as degraded matter, sludge, contaminants, etc., by extraction treatment of a waste oil or waste grease with an organic solvent through a plastic thin-film, followed by removing the solvent.  
     CONSTITUTION: A waste oil or waste grease such as that from lubricant, electical oil, various process oils, etc. is held in a cylindrical plastic thin-film of about 20μ thick, made from e.g. a polypropylene-polyethylene copolymer. The bottom of the film is then immersed in an organic solvent such as petroleum ether; and from the upper part, petroleum ether is made to flow down continuously to extract a pure lubricant component alone from the waste. The extracted component is then warmed to distil the petroleum ether off, thus recovering the pure oil and the petroleum ether respectively.

Abstract: PURPOSE:To obtain a low-cost ink jet printer of a simple structure which provides no change with time by providing a electrodes at opposed positions in a nozzle, high-conductivity ink supplied to an area between the electrodes and a voltage application device for applying a voltage between the electrodes. CONSTITUTION:A top electrode 1 and a bottom electrode 3 are installed in a head 7. The bottom electrode 3 is insulated from ink 4 using an insulation film 2. However, part of the bottom electrode 3 is exposed right under the opening of a nozzle 5. The top electrode 1 and the exposed part of the bottom electrode 3 are opposed to each other through the ink 4. If a voltage is applied to an area between the top electrode 1 and the bottom electrode 2 from a power supply, the ink 4 becomes energized. In this case, the ink 4 is of high conductivity. Consequently, the ink 4 is allowed to evaporate and spurt out, resulting in printing. The heat of evaporation which allows the ink equivalent to a single dot of print pixel is 1 to 3muJ and the conductivity of ink is 10<1> to 10<4>s/m. However, the generally used water ink has the conductivity of 1s/m or less. Therefore, it contains a dispersed high-conductivity material so that the conductivity is kept at a specified level.
